Renal involvement in Systemic Lupus Erythematous (SLE) patients is one of the
leading causes of morbidity and a significant contributor to mortality. It's
estimated that nearly 50% of SLE individuals develop kidney disease in the first
year of the diagnosis. Class IV lupus nephritis (LN-IV) is the class of lupus
nephritis most common in Colombian patients with SLE. Altered miRNAs expression
levels have been reported in human autoimmune diseases including lupus.
Variations in the expression pattern of peripheral blood circulating miRNAs
specific for this class of lupus nephritis could be correlated with the
pathophysiological status of this group of individuals. The aim of this study was
to evaluate the relative abundance of circulating microRNAs in peripheral blood
from Colombian patients with LN-IV. Circulating miRNAs in plasma of patients with
diagnosis of LN-IV were compared with individuals without renal involvement (LNN
group) and healthy individuals (CTL group). Total RNA was extracted from 10 ml of
venous blood and subsequently sequenced using Illumina. The sequences were
processed and these were analyzed using miRBase and Ensembl databases.
Differential gene expression analysis was carried out with edgeR and functional
analysis were done with DIANA-miRPath. Analysis was carried out using as
variables of selection fold change (?2 o ?-2) and false discovery rate (0.05). We
identified 24 circulating microRNAs with differential abundance between LN-IV and
CTL groups, fourteen of these microRNAs are described for the first time to lupus
nephritis (hsa-miR-589-3p, hsa-miR-1260b, hsa-miR-4511, hsa-miR-485-5p,
hsa-miR-584-5p, hsa-miR-543, hsa-miR-153-3p, hsa-miR-6087, hsa-miR-3942-5p,
hsa-miR-7977, hsa-miR-323b-3p, hsa-miR-4732-3p and hsa-miR-6741-3p). These
changes in the abundance of miRNAs could be interpreted as alterations in the
miRNAs-mRNA regulatory network in the pathogenesis of LN, preceding the clinical
onset of the disease. The findings thus contribute to understanding the disease
process and are likely to pave the way towards identifying disease biomarkers for
early diagnosis of LN.
